REMOVABLE SHOE-HEEL.

Specification of Letters Patent.

Patented July 24, 191?.

Application filed February 27, 1917. Serial No. 151,207.

To all whom it may concern:

Be it known that I, J osnrrr SZTARI, a subject of the King of Hungary, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Removable Shoe Heels, of which the following is a specification.

This invention relates to new and useful improvements in removable shoe heels. V

The primary object of the invention is the provision of a heel for foot wear formed of any desirable material and readily attached .to and detached from the heel portion thereof.

A further object of the device is to provide a detachable heel tread member for a shoe so that wearing surfaces of different material may be provided for the shoe heel, a desirable form of tread such as rubber being thereby readily employed when found desirable. j

A still further object of the device is to provide a removable heel that is easy and inexpensive to manufacture but which is adapted for instant attachment to a shoe in firm operative position and while other objects will further appear, the device con sists of a novel arrangement of parts hereinafter fully set forth.

In the drawing forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views,

Figure 1 is a side elevation of the rearportion of a shoe provided with the present device, the latter being illustrated in central. longitudinal section.

Fig. 2 is a front elevation of the removable tread portion of the device.

Fig.3 is a top plan view thereof.

Fig. 4 is a transverse sectional view taken upon line IVIV of Fig. 1.

Fig. 5 is a perspective view of the locking cross head detached.

Fig. 6 is a perspective view of the releasing bar for the cross heads.

Fig. 7 is a perspective view of one of the bearing plates employed.

Fig. 8 is a perspective view of one of the attaching hooks.

Referring more in detail to the drawing it will be understood that the device is serviceable in connection with any form of foot wear such as the shoe 10 having an upper 11 and a sole 12, the device broadly consisting of a heel layer or lift 13 fixedly secured to the rear heel portion of the sole 12 and having a removable tread plate or block 14 carried thereby.

The tread block 14 is of the general shape of the usual form of heel and is provided with a central longitudinal slot 15 in its upper face 16 as well as a transverse slot 17 spaced rearwardly therefrom in a perpendicular plane with respect thereto. A locking cross head 18 is arranged in the slot 17 shiftable transversely thereof with the connector portion of the same adapted to project to normally lie beneath a forward top flange or overlying edge 20 provided for the slot 17. Upwardly extending hooks 21 are carried by the opposite ends of the connector 19 for overlying the said flange 20 and project within spaced sockets 22 in the layer face of the heel lift 13 for normally engaging over keeper ledges 23 at the lower forward edges of the said sockets. The reception of the adjacent portions of the flange 20 and ledges 23 within the cutaway forward sides 39 of the cross head hooks 21 provides a locking means of great strength when the device is normally assembled.

A releasing bar 24 is slidably positioned axially through the slot 15 and through the perforations 25 and 26 arranged through the block 14 in axial alinement forwardly and rearwardly of the slot 15. The forward end of the bar 2 1 projects forwardly and centrally of the concave forward face 27 of the block 14 while the rear end of the bar is threaded within a central opening 28 in the cross head connector 19. A shoulder 29 is adjustably secured to the bar 24; within the slot 15 while an expansion spring 30 is arranged within the said slot surrounding the bar and tensioned between the shoulder 29 and the rear end wall 31 of the slot 15.

Securing hooks 32 are attached by hold fast devices 33 to the forward face 27 of the heel block 14 adapted to extend upwardly into forwardly opening notches or recesses 34: in the heel lift 13, the said hooks overlying the forwardly projecting bottom ledges 35 of the recesses 34 when the device is operatively arranged. The bearing plates 36 having mounting prongs 37 are flatly secured to the upper inner sides of the ledges 2-3 and 35 adapted to be contacted by the hooks 21 and 32 respectively.

14 is detached as shown in Fig. 3, the bar 38 and the forward end of the bar 24 may be pressed and the block applied to the lower face of the heel lift 13 with the forward hooks 32 overlying the recess ledges 35 and with the cross head 18 positioned as illustrated by dotted lines in Fig. 1. By releasing the bar 24:, the spring 30 projects the bar and cross head forwardlyengaging the hooks 21 with the socket ledges 23 with the device in its operative position attached to the lift 13. WVhen desiring to remove the block 14: it is only necessary to press rearwardly upon the bar 38 thereby releasing the cross head and allowing the block tobe detached. 7

A serviceable structure is arranged by means of which tread blocks of different material such as rubber, composition, and leather may be provided for the same shoe rendering the shoe serviceable for a multiplicity of uses.

What I claim as new is:

1. A shoe heel comprising a mounting layer having recesses and sockets therein, a tread block having perpendicularly arranged slots in its upper face, a cross head shiftable longitudinally of the block arranged within one of the said slots having hook portions adapted for engagement within the said sockets, projecting hooks carried by the forward end of the block adapted for seating within the said recesses, an operating bar for the said cross head longitudinally shiftably arranged through the other of said slots and a locking spring for the gross head operatively attached to the said 2. A device of the class described comprising in combination with a shoe, a heel lift carried thereby having recesses at its forward end provided with forwardly project ing bottom ledges, a tread block having a transverse slot in its upper face provided with an overhanging flangeat its forward edge, a cross bar forwardly and rearwardly shiftably arranged within the said slot having a connector adapted for normally seating beneath the said flange and further having upwardly projecting attaching hooks overlying the said flange, a keeper means for the said cross head hooks provided upon the heel '1 lift and operating means for the said cross head.

3; A device of the class described comprising in combination with a shoe, a heel lift carried thereby having recesses at its forward end provided with forwardly projectslot therein, a releasing bar extending axi ally through the longitudinal slot secured at its rear end to the cross head and having its forward end projecting forwardly of the block, a shoulder adjustably secured tosaid bar within the said longitudinal slotand a positioning spring tensioned between said shoulder and the rear end of the longitudinal slot.

j 4. A device of theclass described compris ing a heel -lift havin'gsockets therein provided with bottom ledges, a tread block adapted for flat engagement-beneath the heel lift with a slot in registry with the said sockets, a rearwardly projecting flange a1 ranged at the forward edge of the said slot in alinement with the said ledges a locking cross head rearwardly shiftably arranged within said slot having a connector normally positionedbeneath the said flange and with end hooks positioned within the said sockets overlying the said flange and ledges when the block is attached to the lift and combined normal positioning and releasing means for the said crosshead.
